49ers beat division rivals Seattle to top NFC West

Brock Purdy has thrown for 255 yards and three touchdowns, and the San Francisco 49ers never trailed in a 36-24 victory over the Seattle Seahawks.

Deebo Samuel had a 76-yard catch-and-run touchdown and finished with three catches for 102 yards for the defending NFC champions (3-3), who moved into a tie with Seattle (3-3) for first place in the NFC West after an uneven start to the season.

George Kittle added five receptions for 58 yards and two scores on Thursday night for the 49ers, who beat the Seahawks for a sixth straight time. Kyle Juszczyk added a late TD run, and he and Kittle both celebrated their scores by leaping into the stands to embrace their wives, who were sitting together in the first row.

Matthew Wright, who joined San Francisco earlier this week to replace injured kicker Jake Moody, had a trio of first half-field goals from 25, 41 and 35 yards.

Geno Smith passed for 312 yards and a touchdown but was intercepted twice, and the Seahawks lost their third straight after a 3-0 start under first-year coach Mike Macdonald.

Four days after blowing a 23-10 halftime lead and losing to division rival Arizona, San Francisco fended off a second-half challenge by Seattle, who got a boost from Laviska Shenault Jr.'s 97-yard kickoff return for a touchdown in the third quarter.

After the 49ers punted, Smith led a 94-yard drive and Kenneth Walker III scored from one yard out to get Seattle within 23-17.

But Smith's second interception, this one by Renardo Green, set up Kittle's second TD of the game and a 29-17 lead for the Niners.

Smith found Tyler Lockett for a nine-yard scoring pass with 1:44 left to narrow the score to 29-24. San Francisco responded with Isaac Guerendo's 76-yard dash downfield that led to Juszczyk's six-yard TD run.

Seattle's struggles with the run game continued, with the team finishing with 20 carries for 52 yards — 32 by Walker.
